Application filed October "I, 1920.y

To all fui/0m t may con ccmv Be it known that lf. (ffii/,V citizen otl the United States, resioinpj` at Webster Groves., cit. louis Sou-stv, oscuri, have invented new and useful linprovements in iltutoinobile Radiators, oi'f which the 'following is a sirieciication.

This invention relates to automobile radiators.

The primary object of the invention is to provide an improved means igor heatng the water in the radiator to prevent freezing.

e, nothcr object oit the .invention is to provide means tor stirring or apitating the Water when the engine is running.

In the drawings, in which l have shown the invention,

Fig. l is a plan view.

Fig'. 2 is a vertical cross sectionalview `on the line 2 2 of JF l.

F is a sectional view on the line 3-3 olz Fig. 2 showing a :torni of valve for controlling the heat.

As shown, the radiator l is arranged to contain Water. ln the lower aart ot the radiator lt provide a heating chamber 2 and in the opposite part oit the radiator a heating chamber 3. Heat is delivered into the lower heating chamber 2 `trom a burner e which is conventionally shown Fig. l. l may employ any appropriate torni of burner and do not restrict myself to any particular type. lleat from the burner 4l is conducted into the chamber 2 through a passage 5 and from the chamber 2 heat is conducted into the chamber 3 through a passage 6. lThe chamber 2 is provided with a regulating device to prevent ver-heath@ of the Water and to discharge the heatW air when the temperature reaches a predeteu mined degree oiE heat. showin the passage 7 extends :troni the chamber 2 and encloses a valve 8 which is normally held upon its seat in closed position by a spring- 9. When the pressure Within the chamber 2, due to the increase of heat therein, reaches the desired degree the valve 8 'is forced open by the pressure oit the heated. air permitting the hot air to pass out Bv use of this device freezing l ot the Water in the radiator may be prevented and the may be heated before starting the car, when desired.

My invention also comprises means for agitating the Water to maintain proper cir culation When the car is running.

radiator comprises a numl0 open at their upper and lower ends and perinittinp;` Ytree passage oi `the water therethrough. rllhe tubes l0 i lined with either isinglass or mica 1l. t 's known that Water does not closely ad-V here to either isinglass or mica and does not readiltT Afreeze in connection therewith. l provide also a pair of crank shafts, one of which is arranged horizontally above the ends .ot the tubes l0 and supported horizontall;T belowy the tubes l0. The upper cranlr shaft l2 is journaled `in bearings in supports 13, rthe supports lf3 the iorin'cf partitions forming1 chamhers into which the ends of the upper shaft extend. The outer Walls of the chambers have openings provided With sliding closures livhich may be moved to open position to afford access to the bearings ot the crank The lovver crank shaft l5 is supported in bearings in supports 16 in the torni ot partitions forming chambers which closed from the Water in the radiator and into which the ends of the crank shaft lextend. The outer Walls of the lovver chambers have openings provided vvithslid.` ing closures 17 which be moved to open position to adord access to the bearings ol' the shaft l5.

The cranks of the shafts l2 and l5 are connected b v agitator rods 18 which extend through the tubes l0. llVhen the shafts 12 and are in rotation the rods 18 are oscillated vertically, thereb`VT agitating the Water in the tubes `l0 and causing the Water to circulate so that the water is more quickly heated and prevented from freezing.

rllhe end of one ol'l the crank shafts, Which in the present case is the crank shaft 12, is

els shown, the her of vertical tubes provided with a beveled gear i9 meshing with a 20 on the end of a drive shatt' one ot which is It is free from Complications, it is ot economical construction and may be easily embodied within an automobile.

I do not restrict myself to unessential features, but what I claim and desireto secure by Letters Patent, is

l. In a radiator', a water chamber, a number 't heat chambers within and spaced from the walls ot the water Chamber permitting` the water to Contact with different walls thereof, a passage through one side ot the water chamber tor conducting heated air through one of the heat chambers, a pas sage from the heat chamber into which the heated air 1s conducted 'lor conductin 4heated air into the other heat chamber, Vand a device in Connection with one ot said heat chambers arranged to yield to the pressure ot the heated air to permit heated air to pass from said chamber.

In a radiator, a water Chamber, a number of heat chambers within the water chamber, means for delivering heated air into one of the heat chambers, a passage ier eonducting heated air from the First-named heat chamber to the other one, a passage for oonduoting the heated airout ot said heat chambers, and means for controlling said lastnamed passage. l

8. In a radiator, a water chamber, a heat chamber within the water chamber, means tor delivering heated air into the heat chamber, and devices operated by the engine tor stirring the water in the radiator.

L In a radiator, a water chamber, a number of heat chambers within the water chamber, means 'for delivering heated air into one of the heat chambers, a passage for Conducting heated air from the )first-named heat chamber to the other one, and devices operated by the engine for stirring the water in the radiator.

5. In a radiator, a water chamber, a number of heat chambers within the water chamber, means for delivering heated air into one of the heat chambers, a passage tor conducti ,asi ,04a

ing heated air from the first-named heat chamber to the other one, a passage for conducting the heated air out of said heat Chamber, and devices operated by the engine tor stirring the water in the radiator.

6. In a radiator, a water chamber, a number ot heat chambers within the water Chamber, means Jfor delivering heated air into one ot the heat chambers, a passage for conducting heated air from the iirst-named heat chamber to the other one, a passage for conducting the' heated air Vout of said heat chambers, means for controlling said last named passage, and devices operated by the engine for stirring the water in the radiator.

7. In a radiator, a crank shaft, means for rotating said crank shaft, and a number of elements operated by said crank shaft tor agitating the water in the radiator.

8. A radiator, comprising a radiator shell, tubes 'forming connections between the upper and lower portions lol the radiator shell, a shaft within the upper vportion of the radiator shell, and elements in connection with said shaft and extending downwardly therefrom into said tubes tor agitating the water in the radiator.

9. A radiator, comprising a radiator shell, tubes connecting` the upper and lower portions ot the radiator shell, a shaft within the upper portion of the radiator shell, means for rotating said shaft, and elements operated by said shaft for agitating the water within the tubes.

10. A radiator, comprising a radiator shell, tubes connecting the upper and lower portions ot the radiator shell and forming communications ttor the passage ot water, a crank shaft within the upper portion of the radiator shell, a eranlr shaft within the lower portion ot the radiator shell, rods connecting said crank sha-tts and extending through said tubes, and mechanism for rotating one of said shafts to operate the tubes.
